Dr José Francisco Zurita (IFIC - Univ. of Valencia and CSIC (ES))

Dark showers

In this talk we will present the reinterpretation of the CMS emerging jets (that is, long-lived dark pions belonging to a strongly interacting dark sector), published in JHEP 01 (2024) 034 (arXiv:207.04847) and will show that particularly this search can set meaningful bounds on scenarios where the SM Higgs boson mediates between the visible and dark sectors. In particular we find that for...

26. Exploration of b-philic SVJ and new discriminating observables

Deepak Kar (University of the Witwatersrand (ZA))

Dark showers

After the first round of SVJ experimental results, the focus has shifted to exploring more specific topologies, as well as attempts to design more sensitive observables. In this presentation, we will cover an exploratory study of SVJs produced preferentially with bottom quarks, including looking at the sensitivity from current public results. The advantage of using variable radius jets will be...

24. Probing new signatures for semi-visible jets at the LHC

Cesare Tiziano Cazzaniga (ETH Zurich (CH))

5/17/24, 11:40 AM

Dark showers

The Hidden Valley scenario consists of a set of models where the Standard Model is accompanied by a Hidden Sector and connected with it via a heavy mediator or a weak coupling. If realised in nature, the Hidden Valley scenario may result in unusual and little-studied phenomena at the LHC. Under the assumption of a QCD-like confining dark sector, novel experimental signatures emerge,...

54. Foundation Models as a new tool to uncover the dark sector?

Joschka Birk (Hamburg University (DE))

55. SIFTing for dark shower signals

William Shepherd

5/17/24, 12:15 PM

I present ongoing work seeking to identify the presence of dark shower phenomena in otherwise ordinary-seeming jets using jet substructure techniques with a particular focus on the recently-proposed SIFT algorithm. The aim is to explicitly identify the mass scale signature of the dark shower products which then promptly decay back into SM quarks, giving effectively normal-looking SM jets. This...
